WJEC GCE AS level Biology Unit 2 (from 2008 onwards)

This presentation is hosted by myself, but it is entirely edited by some of my students using resources they have found, discovered or made themselves. If you want to help edit this feature, contact me and I can send you a link to do so!

2.1 Classification

Modern biological classification has its root in the work of Carolus Linnaeus, who grouped species according to shared physical characteristics. These groupings have since been revised to improve consistency with the Darwinian principle of common descent.

2.4 Reproductive Strategies

Reproduction is the biological process by which new "offspring" are produced from their "parents". Reproduction is a fundamental feature of all known life. The known methods of reproduction are broadly grouped into two main types: sexual and asexual.
